CVE-2026-31600

Summary of CVE-2026-31600 : Linux kernel arm64 memory management vulnerability where invalid large leaf mappings could cause a kernel panic due to mis-handling of cleared PTE_VALID bits. Publicly disclosed details describe the root cause in arm64 mm: handling invalid large leaf mappings and the o...

CVE-2026-31600 arm64: mm: Handle invalid large leaf mappings correctly

In the Linux kernel, the following vulnerability has been resolved: arm64: mm: Handle invalid large leaf mappings correctly It has been possible for a long time to mark ptes in the linear map as invalid. This is done for secretmem, kfence, realm dma memory un/share, and others, by simply clearing...

CVE-2026-31573

The vulnerability CVE-2026-31573 affects the Linux kernel media: verisilicon hantro_vpu driver. When built as a module, incorrect use of the __initconst annotation frees data prematurely, and non-init probe code later accesses this freed data, causing a kernel panic (page fault) during hantro_pro...

CVE-2026-31510

A flaw was found in the Linux kernel's Bluetooth L2CAP Logical Link Control and Adaptation Protocol module. This vulnerability, a null pointer dereference, occurs in the l2capsockreadycb function because it fails to validate if a pointer is null before attempting to use it. An attacker within...

CVE-2026-31507

A flaw was found in the Linux kernel's Stream Control Transmission Protocol SMC module. A local user can exploit this vulnerability by using the tee2 system call to duplicate a splice pipe buffer, leading to a double-free condition. This double-free can result in a use-after-free error and a kern...
